regioisomers. The collective data, including deuteriumlabelingstudies, are consistent with a catalytic mechanism involving olefin–dione oxidative coupling to form an oxa-osmacyclopentane, which upon reductive cleavage via hydrogentransfer from the secondary alcohol reactant releases the product of carbinol C-alkylation with regeneration of the ketone.

development of enantioselective C−H activation reactions by desymmetrization. However, the requirement for the presence of two chemically identical prochiral C−H bonds represents an inherent limitation in scope. Reported is the first example of kinetic resolution by a palladium(II)‐catalyzed enantioselective C−H activation and C−C bond formation, thus significantly expanding the scope of enantioselective C−H
